AUTOMOBILE ELEVATOR.

Application led .Tuly 6, 1923. Serial No. 649,889. y I v vMy invention relates to apparatus forV raising automobiles or other vehicles a sufficient distance'above the floor of the garage or the like to permit ready access to the same in vmaking vrepairs or doing other work in connection with automobiles. An object f the invention is to generally improve elevators of the type having inclined runways and a carriage for co-operation with the runways, and which is operated automatically by the power or momentum of the vehicle to be raised.

A. further object of the invention resides in the construction of suoli an elevator which will successfully'operate with practically all types of automobiles now on the market.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings, inwvhich: Figure 1 is a side elevation of the device partly broken away.

Figure 2 is a view similar to Figure 1, showing the parts in a slightly different position.

Figure 3 is a view similar to Figure 1, showing the carriage completely elevated.

Figure l is a plan view of the device partly broken away.

Figure is a front elevation of the carriage.

Figure G is a side elevation of the frontl portion of the carriage, and

Figure 7 is a front elevation of the base or trackway.

Referring to the drawings more in detail, the numeral 1 indicates the base structure of the apparatus and comprises the longitudinal members 2 and transverse brace members 3. Suitably secured to the side members 2 at the rear ends thereof are the channel members 4 which terminate in the upwardly inclined portions 5 supported by the standard 6. These channel members 4 provide suitable tracks for the rear wheels carriage to be later described.

At the forward end of the base structure 1 are secured the channel members 7 'which' form tracks for the forward wheels ofthe carriage and which are inclinedfupwardly and then continued in a horizontal direc-` tion, as indicated at 8. The lforward ends of the horizontal portions are 'v curved up-` wardly on a radius somewhat vgreater than the radius of the carriage wheels to provide a gradual stop for the latter. Standards 9 and 1() are provided lforv supporting thej tracks 7-8 in elevated position.

For co-operation rwith ,the basev structure and tracks I have provided'a carriage indi,- eated generally bythe numeral 1.1'and comprising a substantially .rectangular frame formed of longitudinally extendingchannel members 12 and transverse channel members 13.n A floor orflr'ilatform`14 is secured to the rear end of the carriageffranlie", 11 for the purpose 0f receivin'gthe differential .housing of Athe vehicle bein "liftedl'- The carriage is supported on w eelsV which ride on the tracks 4 and 7 previously described and which are suitably `journaled in the channel members 12 of the carriage.

In order that the carriage may be engaged and carried forward by the vehicle being lifted, I have provided a pair of leaf springs 16 secured to each side of the carriage on the crossbar 17. These springs are inclined upwardly, but are substantially straight and are provided attheir forward ends with hooks 18. Intermediate the springs 16 and also mounted on the crossbar 17 is a third spring 19 provided with a hook 20 and an upwardly curved or cam portion 21. The resiliency of the spring arms 16 land 19 normally holds them in the inclined positions shown in Figure 6, but thefy may be drawn down to inoperative position and held by chains 22 which terminate in hooks 23, and which may be passed around a portion of the carriage and secured to itself.

Pivotally mounted on the base structure 1 is a ratchet bar 24: provided with teeth 25. This bar extends through an aperture 26 in the downwardly extending plate 27 mounted on the forward end of the carriage 11 and (zo-operates therewith to prevent backward ino-vement of the carriage.

Supporting blocks 28 are secured to each of the channel members 12 of the carriage at the forward ends thereof and provide suitable rests for the front axle of the vehicle being raised.

In operation, the carriage being in the The distance betweenathe"inclinedftracksf;

and 7 is such that the forward wheels 15 of the carriage ,will first ride up tleiiicl-ine- 7,.

thus permitting the rearwheels :to remain on the ground Vand givea" forward move'- mentpf the vehicle lduringa part of the movement.' "I`11e`rear wheels l5 oftheifggenw reach the foot. of the inclined traqlfs `51fandfithe remainder of theliftmg. navement isfcompleted by the momentum of. the f vehicle, 'the front `wheels f the carriage, fcdurfse, vccntiimiin'g "along the track `a.

-Wh'a't I Aclaim as new and desire to secure by ,Letters Patent is:

1'.' In alvehicle elevator, including inclined tracks and a carriage for gro-operation 'theres` 61 with, an inclined resilient member secured to the forward end of said carriage,- a projeef', tionon the forward end of said member, and a cam portionearried by said memberintermediate the ends thereof and adapted to be 6` engaged by a portion of the vehiclebeing raised. 2. In a" vehicle elevator, including inclined tracks and a carriage-for co-operation a therewith, an inclined leaf springliaving one 7 end secured to. said carriage, a lug on the fre'e end of ksaid leaf-spring, andan upwardly'.curved portion onV said spring ;inter .mediate the ends thereof'adaptedto'been-4 gaged by a portion of the vehicle; being- 7, raised. i l

3.l In "a vehicle elevator, includingdn-v cilined tracksa'nd a carriage for cox-operation: therewith, 'a pair-of inclined. resilient 'meml bers secured to the carriage at fthe usides 8| thereof, land A'a,tl1`ird y resilient` member se' cured to `the carriage intermediate-theafirst named resilient members, one .ofwsaid resilient members being provided with acamLintermediate its ends and the other resilient e; members being vsubstantially straiglrt,.and hooksI formed on the ends of all of said resilient members. y 4.v In a vehicle elevator, including. inclined tracks and a carriage for cofoperation 91 therewith, a plurality of upwardly inclined spring' members having` one. cnd..secured to the forward end of said carriage, hooks formed on the free ends of said spring inembers, a cam formed on one of said members 9i intermediate the ends thereof, and means for securing any of said spring members in inoperative position.
